Good people, Bad things

Prof. J brought up a good point that sometimes bad things happen to good people. These obstacles in life are what people like to complain about because they want life to come easy. In reality, life is never easy. If we take a closer look into these situations though, are they all bad things? Or rather, should we worry about them being bad? Maybe the challenges that we perceive as bad things are steps to something coming that is good. Perhaps there is something better in store and all the bad things that lead up to that good thing makes it all worthwhile. It also might be difficult to tell what things are supposedly bad and what are good because everyone's view or opnion of good and bad could be different. There are of course, generally good things like helping someone in need and there are general bad things like stealing. So for instance something bad happening to a good person would be that they got money stolen from them. But maybe a few weeks or even days later, they win a brand new car. From a different point of view, maybe after getting money stolen from them the good person gets the opportunity to help at an orphanage and realize that there could be worse things than losing some money.

I remember when reading Pojman I read something about "all opinions are true." I get what this sentence is saying but my question is:

Is saying that all opinions are true like stating an oxymoron?
